Brisbane has been subject to months of climate protests where activists have glued or locked themselves to roads, fences and bridges - as well as to cars and industrial equipment like conveyor belts and hydraulic pumps.

The proposed laws would give police search and seizure powers for people suspected to be carrying locking devices designed to prevent or delay the removal of protesters from public spaces.

They would also introduce new fines for the use of such devices.

A parliamentary inquiry into the laws was told more than 30 dangerous devices have been forcibly removed from protesters.

Laws fast-tracked

Premier Annastacia Palaszczuk said in August that laws were being drafted to stop use of the dangerous devices.

Ms Palaszczuk vowed to fast-track the legislation, saying she wanted the laws in place by the end of the month.
